PEDAL-OPERATED MECHANISM.

Specification of Letters Patent.

Patented Jan. 6, 1920.

To all whom it may concern:

lle it known that we, DANIEL Brennan strain, a citizen oi the United States, and a resident of the borough of Manhattan, city, county, and State 01'' New York, and JACOB Fiscnnn, a citizen of the United States, and a resident oi Roseville, Essex county, State oft New Jersey, have jointly invented certain new and :setul improvements in Pedal-Operated lliechanism, of which the following is a description.

This i'm'ention relates to pedal-operated mechanism ifor sewing machines and the like, and has for its object to enable the pedal to be readily folded up, out of the way, so that the floor may be swept thoroughly under the sewing machine or other m chanism beneath which the pedal is located.

To this end, the invention consists in certain features of construction and relative arrangement, as will be described hereinafter and particularly pointed out in the appended claims.

lVithout intending to limit ourselves to the specific example shown (which may be modified in various ways while remaining within the scope of the appended claims), we will now explain in detail the preferred emhodiinent illustrated by the accompanying drawings, in which Figure l is a perspective view of the novel pedal arrangement; Fig. 2 i; a side elevation of the lower part of the device, with the pedal swung up to the inopative position; Fig. 8 is a. partial horizonfill ll-Lll section substantially on line 3-3 or" Flg.

2, but with the pedal swung down to its operative position; and Fig. at is a partial vertical section on line i l of Fig. 3.

The mechanism is illustrated in connection with a clutch of a character well-known in the operation of sewing machines. A designates a post with a suitable bracket B to which is pivoted at D a lever E having an arm ll controlling the position of a clutch member located in the casing F and permanently driven in any well-known or approved manner. Another arm E of said lever carries the usual brake shoe (not shown) adapted to engage the customary pulley (not shown). J is the customary belt extending from the pulley upwardly to the sewing machine. In the well-known man ner, swinging the lever E down the lefthand end (Fig. 1) will move the brake shoe to the inactive position and cause the belt J to be driven, while the opposite movement (under the influence of a spring K) will stop the drive of the belt and apply the brake.

The lever E is connected pivotally at L with a downwardly extending actuating rod, preierably extensible ior ready adjustment as by making said rod of two sections M, M, passing through parallel sockets of a connecting member N, to which they are secured by set screws 0. The lower end of the actuating rod is connected pivotally with the pedal I", the pivot Q extending from front to rear. At each side the pedal is provided with lugs or trunnions Pf, P, in transverse ailinement with each other. The trunnion P, 011 the side opposite the actuating rod, simply rests in a stationary open-top socket or hearing R secured to the door. The other lug P extends into a slot S of a preferably cylindrical member S journaled in the stationary bearing B said member S turning about transverse horizontal axis in alinement with the axis of the bearing The member S may be held against axial displacement as shown in Fig. 3, by means of an interior shoulder and by means nuts 'l. screwed on a threaded axial extension 6. The connection of the pedal lug P" with the journaled or swivel member S is efi'ected by means of a pivot pin U which is permanently in exact or approximate alinenlent with the pivot Q, so that the pedal P may be swung readily on the axis of the pivots Q, U, from the normal or operative lower position shown in Fig. l to the inoperative raised position Fig. 2, the open top of the bearing R permitting the pedal to thus swing up to the inactive position, or back to the lower position. Preferably a locking device is provided to hold the pedal in the upper position, for which purpose We may employ a latch V pivoted at W to a bracket X secured rigidly to the actuating rod, the pivot W being parallel to the axis Q. U, or approximately so. This latch is adapted to hook over the side edge of the pedal P opposite to the edge at which the ivot Q, is located. a spring Y serving to hold the latch in looking position. The latch and its carrying bracket may be adjustable vertically along the actuating red, as by passing the rod section M through a vertical 'open-top socket,

opening or socket on the bracket X, a set screw Z holding the bracket in place after to its inactive position, will push the latch V upward, and the latter will then snap back over the edge of the pedal.

It will be obvious that the new construction does not interfere in the least with the usual operation of the pedal in which it swings about the transverse axis of the bearings R, R. in addition to this customary movement, the pedal can be swung about the axis Q, U (see dotted line in 1), and when in the upper position 2) the pedal leaves a clear space on the floor between the two bearings R, it, so that the floor may be swept readily at this place; which is but poorly accessible with the usual pedal constructions.

The construction shown at P, Q, t, S, constitutes a universal connection between the pedal and the bearing R, and while we prefer the construction shown, other forms of universaljoints might be employed.

We claim:

1. In pedal-operated mechanism, spaced stationar bearings one of which has an and a pedal located between said bearings and having at one side a lug or trunnion adapted for engagement with said open-top bearing, and at the other side a universal joint connection with the other bearing, wherebv said pedal may be rocked in said bearings, and also swung up on one bearing and out of the other bearing.

2. In pedal-controlled mechanism, spaced stationary bearings one of which has an open-top socket, a pedal located between said bearings and having at one side a trunnion adapted for engagement with said open-top bearing and at the other side a lug projecting in the opposite d'rection, a swivel mem ber journaled in the second hearing about the transverse axis of both bearings, a pivot pin perpendicular to said axis and connecting said lug with said swivel member, and an actuating rod connected with said pedal at a distance from said lug by a pivot joint the axis of which is in alinement with the axis of said pin.

3. In pedal-controlled mechanism, spaced stationary bearings, and a pedal located. be tween said bearings and connected with one of them by a universal joint, while arranged to be lifted out of engagement with the other bearin i. in pedal-controlled mechanism, space-d stationarybearings, a swivel member connected with one of .said hearings to turn about the transverse axis of both bearings, a pedal adapted for loose engagement with the other bearing so that it may be lifted therefrom, and a pivot pin perpendicular to the axis of said swivel member and connecting said pedal with said members 5. In pedal-controlled mechanism, spaced stationary bearings, a swivel member connected with one of said bearings to turn about the transverse axis of both bearings, a pedal adapted for loose engagement with the other bearing so that it may be lifted therefrom, a pivot pin perpendicular to the axis of the swivel member and connecting said pedal with said member, and an actuating rod connected with said pedal at distance from the swivel member by a pivot joint the axis of which is in alinement with the axis of said pin.

6. In pedal-controlled mechanism, spaced bearings, a pedal having a universal joint connection with one of said bearings and adapted for loose engagement with the other bearing, and an actuating rod connected with said pedal by a pivot oint the axis of which passes through the center of said universal joint.

7. In pedal-controlled mechanism, spaced bearings, a pedal havin a universal joint connection with one of said bearings and adapted for loose engagement with the other nearing, an actuatin rod connected with said pedal loosely on the side adjacent to the universal joint bearing, and a latch carried by said rod and adapted to engage the pedal when swung away from the other bearing.

8. In pedal-controlled mechanism, a pedal universally supported at one side so that it may be rocked and also swung out of the way upwardly.

9. In pedal-controlled mechanism, a pedal universally supported at one side so tiat it may be rocked anl also swung out of the way upwardly, a su ort adapted to be engaged by the other side of the pedal when the latter is lowered, and a latch for locking the pedal in its raised position.

10. in pedal-controlled mechanism, a. pedal universally supported at one side so that it mav be rocked and also swung out of the way upwardly, and a latch for locking the pedal in its raised position. i

11. In pedal-controlled nechanisin, a pedal universally supported at one side so that it in?" be rocked and also swung out of the way upwardly, and a support adapted to be en aged by the other side of the pedal when the latter is lowered.

In witness whereof we have hereunto set our hands this 7th day of April. 1919.
